Best interconnect for bass only


I have a four speaker system, with one amp running the two bass towers. What I am looking for, would be the "best" ic's to run from the preamp to the bass amp considering the amp and speakers are running bass only. I have had some feedback that a silver ic would be the way to go, as it would be the tightest controled bass. Thoughts!!?

Let me add some confusion to this discussion.

Actually, I disagree in general with the first response, but agree with some of his specific points.

Just for shits and giggles I tried different cables from my 2-channel system in my HT system's sub. Specifically I hijacked the Acoustic Zen Matrix II, Acoustic Zen Silver Ref II and Audience AU24 to test with my HT sub. In this test the AZ Silver Ref definitely passed a tighter, firmer bass than the other two copper cables and this was with a signal of 100Hz down.

I did this goofy experiment only out of boredom. Like others here I preferred using Analysis Plus Solo and did all the adjustments with sub placement and crossover slope shaping. I found this to be the best way for me.

I also agree with the initial respondent that if substituted in a full range set up, you may perceive tighter bass with a silver cable because of its overall affect on the full sound spectrum.

I hope this doesn't confuse you, heheh.
Listen & heed 1st response---Vandermeulen---I wish I had all the money I wasted on this kind of pursuit:-(
Thanks for all the input folks. I can definately see how an ic on the mid/tweeter would change midbass and our perseption of how the bass sounds. I am actually very happy with my bass, the Genesis bass towers are adjustable on frequency, high and low pass and volume, so I don't have any issues with bass..........just thought that maybe there was an opportunity to fine tune the bass, by getting some holy grail in bass cable. Trying out different ic's on a sub is a good idea.......I think that is essentially what I am asking, what is the best ic for a sub?? I think I am hearing from most of you, that there isn't a big change, like there can be on the top end.....when it comes to changing ic's on a sub.
But most importantly Bullot, I/we are not here to disuade you from making a specific decision. You HAVE to try things out for your self. PERIOD. That is how you will help to advise others one day from your own experiences.
